    rotary kilns vs. rotary dryers: what’s the difference?

    While rotary kilns can dry a product, their main concern is not in drying, but simply heating. Rotary dryers are almost always used for drawing moisture out of a material. Typically, they operate at temperatures between 800º – 1400ºF. Rotary kilns, however, are concerned with causing a chemical reaction

    The kiln sitter is a mechanical device used in ceramics to insure the kiln is shut off at the correct time. Pyrometers don’t work well with ceramic projects, because you need to know the “heat work” (temperature and timing) inside the kiln for proper firing. If an automatic controller is not in use, a kiln sitter can function as a sort of
